Description

Technical Field

[0001] The utility model relates to the technical field of chemical waste gas treatment, in particular to a purification tower for chemical industry. Background Art

[0002] Chemical waste gas refers to toxic and harmful gases discharged by chemical plants during chemical production. Chemical waste gas often contains many types of pollutants with complex physical and chemical properties and different toxicities. The role played by chemical waste gas purification towers is becoming increasingly important.

[0003] For example, Chinese patent document CN209348393U discloses a chemical waste gas purification tower, including an air intake pipe, an ozone generator, a purification tower body, a water spray pipe, and a water storage tank. The air intake pipe is fixedly provided with an impeller, a filter screen, and a jet pipe. The top of the filter screen penetrates the air intake pipe and is fixedly connected with a knocking block. The top of the jet pipe penetrates the air intake pipe and is threadedly connected with an air delivery pipe. The other end of the air delivery pipe is threadedly connected with an ozone generator. The right end of the air intake pipe is fixedly connected with the purification tower body. The upper inner wall of the purification tower body is fixedly provided with an infrared heating pipe. The purification tower body is fixedly provided with a water spray pipe. The right end of the water spray pipe penetrates the purification tower body and is threadedly connected with a water delivery pipe. The bottom of the water delivery pipe is fixedly connected with a pump. The exhaust gas purification speed is adjusted by adjusting the speed of the impeller, and the infrared heating pipe can heat the purified exhaust gas to prevent the exhaust gas from condensing directly around the purification tower due to excessive water after being discharged, thereby corroding the purification tower.

[0004] The existing technology has the following problems:

[0025] The nitric oxide in the chemical waste gas is converted into water-soluble nitrogen dioxide through the ozone generator 16, which is convenient for subsequent purification and treatment. The particles in the waste gas are then reduced by the dust reduction mechanism 3. The amount of waste gas entering the purification tower 11 can be changed by the adjustment mechanism 2, thereby changing the purification speed of the waste gas.

[0026] like Figure 2 , Figure 3 As shown, the output end and the input end of the blower 21 are fixedly connected with a connecting pipe 22, the right part of the connecting pipe 22 at the output end is fixedly connected to the bottom of the left end of the purification tower 11, the outer wall of the connecting pipe 22 at the output end is fixedly connected to the inner wall of the jet pipe 17, the inner wall of the connecting pipe 22 at the output end is rotatably connected with a rotating rod 23, and the inner wall of the connecting pipe 22 at the output end is fixedly connected with a connecting plate 221.

[0027] By starting the blower 21, the exhaust gas is transported to the purification tower 11 through the connecting pipe 22. During this process, the ozone generator 16 is started, and the ozone is transported to the connecting pipe 22 through the jet pipe 17, and reacts with the nitric oxide in the exhaust gas in the connecting pipe 22 to convert the nitric oxide into nitrogen dioxide which is easily soluble in water, thereby facilitating the treatment of the exhaust gas. After the exhaust gas enters the purification tower 11, it moves upward and is filtered through the activated carbon net 15 to block the odor in the exhaust gas, thereby achieving the effect of purifying the odor.

[0028] like Figure 2-Figure 4As shown, the bottom end of the rotating rod 23 is fixedly connected with the active bevel gear 24, the outer wall of the active bevel gear 24 is meshed with the driven bevel gear 25, the axis of the driven bevel gear 25 is fixedly connected with the rotating shaft 26, the outer wall of the rotating shaft 26 is rotatably connected to the bottom of the connecting plate 221, the left end of the rotating shaft 26 is fixedly connected with the movable plate 27, the outer wall of the movable plate 27 is rotatably connected to the inner wall of the connecting tube 22 at the output end, the left end of the movable plate 27 is rotatably connected with the fixed plate 28, the outer wall of the fixed plate 28 is fixedly connected to the inner wall of the connecting tube 22 at the output end.

[0029] By rotating the rotating rod 23, the active bevel gear 24 is driven to rotate, so that the active bevel gear 24 and the driven bevel gear 25 are meshed, thereby driving the rotating shaft 26 to rotate, and the rotating shaft 26 drives the movable plate 27 to rotate synchronously, thereby changing the overlapping area between the opening of the movable plate 27 and the opening of the fixed plate 28, thereby changing the amount of exhaust gas entering the purification tower 11, thereby achieving the effect of controlling the flow rate.

[0030] like Figure 2-Figure 4 As shown, the outer wall of the movable plate 27 is fixedly connected with a sealing strip 271, and the outer wall of the sealing strip 271 is slidably connected with the inner wall of the connecting tube 22 at the output end. The bottom of the sealing strip 271 is fixedly connected with a positioning block 272, and the outer wall of the positioning block 272 is clamped with the inner wall of the connecting tube 22 at the output end.

[0031] When the movable plate 27 rotates, the sealing strip 271 is driven to rotate synchronously, and the sealing strip 271 drives the positioning block 272 to rotate synchronously. When the outer wall of the positioning block 272 is separated from the inner wall of the connecting tube 22, a certain resistance is generated. When the positioning block 272 rotates to a certain position, the outer wall of the positioning block 272 is again engaged with the inner wall of the connecting tube 22, thereby determining the rotation distance of the movable plate 27.

[0032] like Figure 2 , Figure 5 As shown, a water inlet 32 ​​is fixedly connected to the right portion of the top of the water tank 31, a water outlet 33 is fixedly connected to the bottom of the right end of the water tank 31, a filter screen 34 is inserted into the top of the water tank 31, a water pump 35 is fixedly connected to the left portion of the top of the water tank 31, and both the output and input ends of the water pump 35 are fixedly connected to water pipes 36, the outer wall of the water pipe 36 at the input end is fixedly connected to the inner wall of the filter screen 34, the top of the water pipe 36 at the output end is fixedly connected to the right portion of the purification tower 11, and a water spray pipe 37 is fixedly connected to the top of the water pipe 36 at the output end, and the right end of the water spray pipe 37 is fixedly connected to the right end of the inner cavity of the purification tower 11.

[0033] Start the water pump 35, and pump water or other liquid out of the water tank 31 through the water pipe 36, transport it to the water spray pipe 37 through the water pipe 36, and then spray it out through the water spray pipe 37, so as to reduce dust on the exhaust gas in the purification tower 11, so that the particulate matter in the exhaust gas falls to the bottom of the inner cavity of the purification tower 11, and the purified gas continues to float upward until it floats into the atmosphere, thereby achieving a purification effect. Subsequently, water or other liquid is added to the water tank 31 through the water inlet 32. During this process, the filter screen 34 filters the water or liquid to filter out impurities and particulate matter therein, thereby avoiding subsequent clogging of the water spray pipe 37, thereby reducing the maintenance cycle of the water spray pipe 37 and preventing the clogging of the water spray pipe 37.

[0034] The working principle of the utility model is as follows: when in use, the blower 21 is started, and the exhaust gas is transported to the purification tower 11 through the connecting pipe 22. During this process, the ozone generator 16 is started, and the ozone is transported to the connecting pipe 22 through the jet pipe 17, and reacts with the nitric oxide in the exhaust gas in the connecting pipe 22 to convert the nitric oxide into nitrogen dioxide which is easily soluble in water, thereby facilitating the treatment of the exhaust gas. After the exhaust gas enters the purification tower 11, it moves upward and is filtered through the activated carbon net 15 to block the odor in the exhaust gas, playing a role in At the same time, the water pump 35 is started, and the water or other liquid in the water tank 31 is pumped out by the water pipe 36, and the water or other liquid is transported to the water spray pipe 37 by the water pipe 36, and then sprayed out by the water spray pipe 37, so as to reduce the dust of the exhaust gas in the purification tower 11, so that the particles in the exhaust gas fall down to the bottom of the inner cavity of the purification tower 11, and the purified gas continues to rise until it floats into the atmosphere, which has a purification effect. In the purification process, the active bevel gear 24 can be driven to rotate by rotating the rotating rod 23, so that the active bevel gear 24 meshes with the driven bevel gear 25, thereby driving the rotating shaft 26 to rotate, the rotating shaft 26 drives the movable plate 27 to rotate synchronously, and at the same time the movable plate 27 drives the sealing strip 271 to rotate synchronously, and the sealing strip 271 drives the positioning block 272 to rotate synchronously. When the outer wall of the positioning block 272 is separated from the inner wall of the connecting pipe 22, a certain resistance is generated. When the positioning block 272 rotates to a certain position, the outer wall of the positioning block 272 is again engaged with the inner wall of the connecting pipe 22, thereby determining the rotation distance of the movable plate 27. By changing the overlapping area between the opening of the movable plate 27 and the opening of the fixed plate 28, the amount of exhaust gas entering the purification tower 11 is changed, thereby controlling the flow rate. Subsequently, water or other liquid is added to the water tank 31 through the water inlet 32. During this process, the filter 34 filters the water or liquid to filter out impurities and particulate matter therein to avoid subsequent clogging of the water spray pipe 37, thereby reducing the maintenance cycle of the water spray pipe 37 and preventing clogging of the water spray pipe 37, thereby greatly improving the user experience.
